Richardson told the judge and courtroom she was "so sorry" before sentencing. The judge said she showed a "grotesque disregard for life" and warned her he can send her to prison for up to a year if she violates probation.

Richardson's defense maintained that the baby was stillborn. Prosecutors argued that she hid her unwanted pregnancy and killed the baby before burying it in her family's backyard.
